Glass fibers are more effective in achieving shear strengthening. Various methods can be used in the reinforcement of polymers using carbon or glass fibers. Some of the methods include curing pressure increase and filler incorporation and vacuum infusion. This paper outlines a comparison among the various rigidising methods using reinforced material to increase the general strength of the materials. The electrical conductivity of the materials has also been analyzed [8]. Curing pressure increase and filler incorporation This ridigising method enhances the through-thickness thermal conductivity of carbon fiber polymer-matrix. This method is used to increase heat dissipation by enhancing the low through-thickness thermal conductivity of carbon fiber polymers. The conductivity is normally raised by 60 percent by enhancing the curing pressure from 0.1 to 2.0 MPa and almost by 35 percent by incorporation of a filler. This was reported in an experiment conducted at Composite Materials Research Laboratory in the University of Buffalo [4]. The experiments were conducted to determine the effect of curing pressure and filler incorporation on the mechanical and conductivity properties on a material. The mechanical test was conducted on a 15-lamina crossply composite plate under flexure using a hydraulic mechanical testing procedure. ...
